Hello everyone,
Today, I set up an Anki syncserver in my Jail. Since the Anki official documentation does not mention how to set it up as a service, I followed the FreeBSD handbook and other users' services as examples to create an rc.d service.
After some testing, it works, but there are a few things I don't understand. I would like to know if this is the correct way to achieve it.
In my Anki syncserver service, the user anki is a nologin shell user. Since they cannot run commands directly, it seems I can only use the precmd method to start the service and use rc_flags inside the precmd (prestart function) to create a PID file.
To avoid everything showing in the terminal, I set the output to /dev/null by
I also don't understand why I have to set
Additionally, to test if the nologin user can run the command without problems, I have to use

${rc_flags} at the end of the rc_flags.Additionally, to test if the nologin user can run the command without problems, I have to use
su -m anki -c cmd. Is there any other method to overcome the nologin shell?

# Add the following lines to /etc/rc.conf.local or /etc/rc.conf

#
# anki_enable: Set to YES to enable anki
# Default: NO
# anki_user: The user account used to run the anki daemon.
# This is optional, however do not specifically set this to an

# Default: anki
# anki_group: The group account used to run the anki daemon.
# This is optional, however do not specifically set this to an
